Be itzknoyvnthat I, JosErnfHRsnsrraN, a citizen of. the "United States,land vresident of. St. Louis, Missouri, have invented certain *neW' andusefulf improvements ,1n

- tween the'easting and the flooring material 'be drained foil2 -int thecasting" from the angeddisk, '1. .The bottom en`d15, of the castingvisjso to the drainjpipe,.eitherl by a Wipe joint aty the line indicatedbythe numeral 1 14, will zishaped tol pbe adaptable vfor.conne'tion.commonly known to the plumbing trade or it Amay be arranged'withvscrew-threads so that. the end can'be attached to avpipe by a suitablecoupling., This featurehowever is immaterial as the essential feature ofmy *invention 'is to arrange a drain to prevent water from 'seeping'down the side'of the casting and staining the ceiling below.

In placing the drain in position the 'same i is embedded in the floor,which Hoor in such instances is preferably-constructed by layingla-bedof tainped cinders, or like material .16, and on. the top' thereof,placea layer'of'concrete17, and on the top thereof,y the Usual tiling 18;orin some instances' a smooth coating" ofcemen't. `And when the 'deviceso placed in. position in the floor and in order to provide 'for properdrainage andin orderto further prevent any seepage from passing down onthe side of the casting` and -to properly drain olf -any such seepageWhich-might pass down the side of. the casting, I llfthe disk lwith.coarse vnuatierial, such-.as pebbles, gravel, cind'ersor""the likeyas`indicated by the numeral 19,- and L mayif desired place i around theCasting .over a plurality of apertures of the holes 13, a ringQO,constructed of some porous material suchl as a vvery fine mesh, felt,sponge or otherl materialfound desirable, and by such arrangement it,Vvvould prevent" any of. the iller' inthe 'ilanged diskfrom passing,rthrough any of the apertures. And further, in 'order to prevent leakageand to make an absolute -l leak-proof connection between the Adisk andthe "casting l may place a gasket. 2l, at the connecting point at-thebaseof the screw- -threads `9. In isonne instances Where it is sorequired and in the eventv of the-concrete becoming cracked :I may embedin the con- /Jcrete a 4sheet of ,pliable material such as sheet may-be'extended' the. entire Vlength and Width of the space occupiedby theshower, and the. lsame `may be slightly inclined so that in theVevent-the 'floor should become cracked and Water seep through thegcracks it would Contact Withthe sheet and be di- 'sheet lead, copper orthe like, 22. This' rected vto the iianged disk and be permitted to passout into the drain through the openingsl 13.

This device is not only adaptable for drains through which rthe water is-permitted to pass anddrain the iloor line when used in' connection withshower` baths but, may be used also inany crn'nectioirl in' bath roomsWhere there might be a possibility of water' -seepingA down between thecastings andI floor. l-'t isa Wellllmown fact that bysuddenchangesoftemperature such as' eX- tremely hot and cold Water striking theeastings that an expansion and: contraction takes place which will causea separation between the bcdy ot the casting and the vmaterial yformingthe floor in which'the' casting isembeddedr and this crack' or space'between:

A Having flly -described my invention what l2claimy is 1. Iny drains of. :theve'lass described. they combination of acasting, a detachable'` flanged shieldy mountedy thereon andapproximately centrally' located, said casting `having a plurality oi?apertures'formed in` itsl walll and cn a level with the inner surface"ofthe shield; a grill. detachably located. in the casting, said castingand shield being embedded in the licor; the said grill being flush'with1the'loor line and a ring of porous material located in; the shieldcovering the apertures for permitting any seepage passing and the iioormaterial to escape into 'and pass o-ut by Way of said casting,substantially as specified.

4: A drain of the classl described comprisa' cylindrical casting, aplurality of apertures formed in the Wall thereof and loeated-l atintervals apart at approximately the center of said casting; an integralflange formed on the outer periphery thereof, a detachable liange shieldresting o'n the integral flange; a' ring' of porous material locatedinthe ianged shield and covering the aperturesformed in the cylindricalcasting; and

a detachable grill located in the top of the A casting, all of. saidparts being embedded and'-incased `in the material forming the Hoor,substantially as specified.

5. A drain ofA the class described comprising a cylindrical casting, itswalls provided witha' plurality of apertures, detachable i-anged' shieldconnected to said casting, its floor line being on a level with theapertures, ay ring of porous material located around the castingcovering the apertures; a bed of porous material placed in the flangedshield through which moisture can freely pass toward the aperturesthrough which said moisture is drained into the casting; all of saidparts being incased and concealed in the material forming the floor,substantially as specified. y
